Electronic Device

1. An electronic device, comprising: a loudspeaker having a second mating surface; and a body portion having a mounting cavity for mounting the loudspeaker, wherein an inner wall of the mounting cavity includes a first mating surface, and the first and second mating surfaces respectively include first and second channels configured to be mutually connected, wherein includes a limiting structure, and a flexible sealing member along a circumferential direction of the first channel, wherein the second mating surface includes a rigid sealing member along a circumferential direction of the second channel, wherein the two mating surfaces are configured to move relative to each other so that the rigid sealing member is mated with the flexible sealing member in a sealing manner, wherein the limiting structure is configured to restrict the flexible sealing member from moving relative to the first mating surface along a first direction, and wherein the first direction is a direction along which the rigid sealing member moves relative to the flexible sealing member.

2. The electronic device of claim 1, wherein the first mating surface includes a mounting groove, the flexible sealing member is in the mounting groove, and a groove wall of the mounting groove forms the limiting structure.

3. The electronic device of claim 2, wherein a depth of the mounting groove is not less than a thickness of the flexible sealing member, and the rigid sealing member protrudes from the second mating surface.

4. The electronic device of claim 2, wherein the flexible sealing member is adhesively fastened to an inner wall of the mounting groove by a first adhesive layer.

5. The electronic device of claim 1, wherein the flexible sealing member is a silicone sealing gasket.

6. The electronic device of claim 1, wherein the second mating surface is integrally formed with an annular convex rib, and the annular convex rib forms the rigid sealing member.

7. The electronic device of claim 6, wherein a side end of the annular convex rib that faces the first mating surface is a smooth arc structure.

8. The electronic device of claim 7, wherein a cross section of the annular convex rib tapers from a side of the second mating surface to a side of the first mating surface.

9. The electronic device of claim 1, further comprising a dust filter between the first mating surface and the second mating surface, wherein the dust filter is configured to block the channel provided on the inner wall of the mounting cavity.

10. The electronic device of claim 9, wherein the dust filter is adhesively fastened to the first mating surface on the inner wall of the mounting cavity by a second adhesive layer.

11. The electronic device of claim 1, wherein the first and second mating surfaces are both inclined surfaces that adapt to each other, and an end of the first mating surface of the mounting cavity that faces an opening is inclined towards the outside of the mounting cavity.

12. A method, comprising: providing a loudspeaker having a second mating surface; providing a body portion for an electronic device, wherein the body portion comprises a mounting cavity, wherein an inner wall of the mounting cavity includes a first mating surface, and the first and second mating surfaces respectively include first and second channels configured to be mutually connected, wherein the first mating surface includes a limiting structure, and a flexible sealing member along a circumferential direction of the first channel, wherein the second mating surface includes a rigid sealing member along a circumferential direction of the second channel, wherein the two mating surfaces are configured to move relative to each other so that the rigid sealing member is mated with the flexible sealing member in a sealing manner, wherein the limiting structure is configured to restrict the flexible sealing member from moving relative to the first mating surface along a first direction, and wherein the first direction is a direction along which the rigid sealing member moves relative to the flexible sealing member.

13. The method of claim 12, further comprising directly mounting the loudspeaker in the mounting cavity from outside in along a depth direction of the mounting cavity.

14. The method of claim 13, wherein the loudspeaker is not inclined during the mounting.

15. The method of claim 12, wherein the first mating surface includes a mounting groove, the flexible sealing member is in the mounting groove, and a groove wall of the mounting groove forms the limiting structure.

16. The method of claim 15, wherein a depth of the mounting groove is not less than a thickness of the flexible sealing member, and the rigid sealing member protrudes from the second mating surface.

17. The method of claim 15, wherein the flexible sealing member is adhesively fastened to an inner wall of the mounting groove by a first adhesive layer.

18. The method of claim 12, wherein the flexible sealing member is a silicone sealing gasket.

19. The method of claim 12, wherein the second mating surface is integrally formed with an annular convex rib, and the annular convex rib forms the rigid sealing member.

20. The method of claim 12, wherein the first and second mating surfaces are both inclined surfaces that adapt to each other, and an end of the first mating surface of the mounting cavity that faces an opening is inclined towards the outside of the mounting cavity.
